1. The problem asks for the number of edges in a right rectangular prism. 2. A right rectangular prism is a 3D shape with 6 rectangular faces, 8 vertices, and edges connecting these vertices. 3. The formula for the number of edges in a rectangular prism is based on its vertices and faces: it always has 12 edges. 4. This is because each of the 6 faces has 4 edges, but each edge is shared by 2 faces, so total edges = $\frac{6 \times 4}{2} = 12$. 5. The problem states the prism has 8 vertices and 6 rectangular faces, confirming it is a rectangular prism. 6. Therefore, the number of edges is 12. 7. The height being greater than the width does not affect the count of edges. Final answer: The right rectangular prism has **12 edges**.
